I got an email from my unis admin team yesterday. Basically there was a student group who arranged a research trip to north Korea. This trip was, allegedly, attended (unbeknownst to the organisers and other attendees) by three BBC journalists who then proceeded to film covertly. The documentary is showing tomorrow night.
The uni is wire adamant than noone in an official capacity knew about he journalists attendance. They maintain that if they had, they would not have allowed it. It really could have put the students in danger. That said, I find it very hard to believe that one of the student organisers didn't know about it, even if no staff did.
